I used to be able to use three finger scroll-up to switch between source/header. Since upgrading to Lion, I it just does a regular scroll. Is there any way to get that feature back?
Aka, it doesn't jump to counterpart when I scroll up / down like it used to.
Apple fixed the issue in Xcode 4.2. So, upgrade your versions.
To create custom gestures, click which input device you'd like to recognize: we'll start with the Trackpad. Then, click “Add New Gesture.” Once you've done this, shift your attention to the bottom of the window. On the left, you can pick a gesture; on the right, an action for the gesture to trigger.
Double-tap with two fingers to open Mission Control. Swipe left or right with two fingers to move between desktops and full-screen apps. Swipe left or right with one finger to show the previous or next page.
On the keyboard, press the Control key and click the trackpad. Two-finger scroll: Slide two fingers up or down to scroll. Pinch to zoom: Pinch your thumb and finger open or closed to zoom in or out of photos and webpages.
This is the correct and best answer. It works. It is posted by "@Buyin" above. Another individual commented that it doesn't work. He is wrong. It works, I've confirmed it. It restores the three finger vertical swipe to switch between interface and implementation files (.h and .m) in xCode in Lion.
From your terminal:
Change to appropriate directory (note, if your Library dir is hidden, in the terminal just type the following: chflags nohidden ~/Library )
1. cd /Users/YOURUSERNAME/Library/Preferences/ByHost
List files so you can see the .GlobalPreferences.XXXX-XXXX-XXXX-XXXX.plist
2. ls -lah
Open that plist file in xcode
3. open -a /Applications/Xcode.app ".GlobalPreferences.XXXX-XXXX-XXXX-XXXX.plist"
Set value to 1 for the key "com.apple.trackpad.threeFingerVertSwipeGesture"
Save the plist file
Log out and back into machine
VOILA!
